Dykstra, 48, allegedly told the women responding to his Craigslist ads the job required them to give massages and then exposed himself, the Los Angeles Times reported Thursday.
An arraignment is set for Sept. 7 in Los Angeles County Superior Court.
Dykstra, who grew up in Garden Grove, Calif., played center field for the New York Mets and helped the team win the 1986 World Series. The three-time all-star also played for the Philadelphia Phillies.
In June, Los Angeles County prosecutors charged him with felony counts in a scheme to obtain luxury cars and for possession of drugs.
Dykstra is also facing federal charges of bankruptcy fraud and obstruction of justice for allegedly concealing more than $40,000 in property being sought by creditors, the Times reported.
